Hmm...this is interesting. I fish Dunlap a lot, and can say that there is really not a lot of underwater vegetation. There are lily pads in certain areas, but no more than in the past & the drawdowns in the past really didn't stop them from coming back. I know there is a lot of "floating" vegetation that I believe is coming from upstream where they clean the Landa park lake and areas downstream. It is interesting if you read the study, it mostly quotes northern lakes and referenced salmon migrations etc. Not sure they really know what they are doing??? & would like to hear a more detailed explanation...like what plants they are trying to kill & what effect this will have on the various species of fish living there...especially during cold spells. I checked the PLDA (Preserve Lake Dunlap Association) website and there is nothing mentioned there, but I seldom find useful info there anyway.
